Danfoss ECL Comfort 200 - P16 Operating instructions

Before you start

How to use this guide

This guide is divided into two parts:

• Daily Use (turn the guide over)

Yellow sections 01 - 09

• Installation and maintenance:

Grey sections 10 and onwards

Save energy - save money - improve your comfort

temperature

The ECL Comfort controller is designed by Danfoss for

temperature control of hot water systems.

The ECL Comfort controller ensures you of the following;

• The hot water temperature will be adjusted to your

personal settings

.

Sketch an outline of your hot water system

The ECL Comfort controller is designed for a wide range of

hot water systems with different configurations and

capacities.

If your hot water system differs from the diagrams shown in

section 10, you may want to sketch an outline of the system

about to be installed. This makes it easier to use the

Installer’s Guide, which guides you step-by-step from

installation to the final adjustments before the end-user

takes over.

Note! The controller is pre-programmed with factory

settings that are shown in the relevant sections of this

guide.

Operating the ECL Controller and the ECL Card

The ECL Card has a yellow side for the daily use and a

grey side for the installation and maintenance.

Both sides of the card are divided into lines representing

the different options of control and programming.

Select the side of the ECL Card you want to

operate.

The light diode below the inserted ECL Card

indicates the chosen side, ie. left light for daily use

and right light for the installation and maintenance.

(See sections 15 and 16).

Installation

Mounting the ECL Comfort

controller

11

For easy access, you should mount the ECL Comfort

controller near the heating unit. Select one of the three

following methods:

• Mounting on a wall

• Mounting on a DIN rail

• Mounting in a panel

Screws and rawlplugs are not supplied.

Mounting in a panel

Connector set: Order code No. 087B1148.

The panel plate thickness must not exceed 3 mm.

Prepare a cut-out with the dimensions 92 x 138 mm. Pull off

the right side of the lid by means of a screwdriver.

Insert the controller into the panel cut-out and fix it with the

two locks which are placed diagonally in two corners of the

controller.

Mounting on a DIN rail

Mounting kit: Order code No. 087B1145.

A mounting kit is necessary to mount the box with the

controller on a DIN rail.

Mounting on a wall

Socket for mounting on wall: Order code No. 087B1149.

Mount the terminal box on a wall with a smooth surface.

Flow temperature sensor

(ESMU, ESMA or ESMC types)

Place the sensor max. 15 cm from the mixing point. In

systems with heat exchanger, Danfoss recommends the

ESMU-type to be inserted into the exchanger flow outlet.

Make sure that the surface of the pipe is clean at the area

where the sensor is mounted.

Do not move the sensor after it has been fastened in

order to avoid damage to the sensor element.

Hot water temperature sensor

(ESMU or ESMB types)

Place the hot water sensor according to the

manufacturer’s specification.

14

Placing the temperature

sensors

It is important that the sensors are mounted in the correct

position in your hot water system.

Special attention should be paid to the following

sensors:

Adapting the ECL Comfort

controller

Accept to set up the selection.

While the setup is in operation, the data transfer-display

will appear.

After initialising, the display will return to the standard

display line C of the yellow side of the ECL Card.

The controller is now ready to control the selected

hot water system. You can make your own

adjustments/settings in daily use and in the basic setup

and change the extended service settings.

Installation

Select the hot water system type printed on your

ECL Card.

Open the lid and switch on the controller. The display

shows the system type.

Adjusting the ECL Card

settings

If several controllers are installed in the hot water system

you can write a title on the ECL Card with a permanent ink

pen.

Changing from one side of the ECL Card to the other

When changing from the grey side of the ECL Card to the

yellow side, you will always enter line C and the standard

display.

Changing from the yellow side to the grey side, you will

always enter line A - Time and date. See opposite page.

General principles

When the controller is connected and operating you can

check and adjust all or some of the basic settings on the

grey side of the ECL Card. Select the grey side of the

ECL Card.

Use the arrow buttons to move from line to line

of the ECL Card, for example line 4:

Use the minus/plus buttons to adjust the

setting(s).

In some displays more than one setting or

value can be adjusted. Use the shift button to

switch between the options.

Set the proportional band

A higher value will result in a stable, but slow

regulation of the flow temperature.

Set the neutral zone to a high value if you can

accept a large variation in flow temperature.

When the actual flow temperature lies within the

neutral zone, the controller does not

activate the motorized valve.

Note! The valve is symmetrically around the

flow reference value.

Basic set-up

If you want to tune the PI-regulation precisely, you can

use the following method:

• Set the integration time (line 5) to its max. value (999 sec.).

• Decrease the value for the proportional band (Line 4) until

the system starts hunting with a constant amplitude (it might

be necessary to force the system by setting an extreme

value).

• Find the critical time period on the temperature recording or

use a stop watch.

This time period will be characteristic for the system, and you

can evaluate the settings from this critical period.

Integration time = 0.85 x critical time period

Proportional band = 2.2 x proportional band value in the

critical time period.

If the regulation seems to be too slow, you can decrease the

proportional band value by 10 %.

Note! Make sure there is a consumption when you set the

parameters.

How to calculate the running time of the motorized valve

The running time of the motorized valve is calculated using the

following methods:

Seated Valves

Running time = Valve stroke (mm) x actuator speed (sec/mm)

Example: 5.0 mm x 15 sec/mm = 75 sec.

Rotating Valves

Running time = Turning degrees x actuator speed (sec/degr.)

Example: 90 degrees x 2 = 180 sec.
